I created my workflow with the help of Grok3 AI. I learned a lot along the way. Grok coded and I tested and reported any errors that appeared. The idea was to use AI to reorganize some of my texts into posts on my WordPress blog and eventually generate these posts with the help of a few keywords. to create a featured image on Pexel and place it in the post. And of course, we did it so that nothing was paid. Just so you know that I’m not a programmer and that this is my first attempt at making something like this. So if I can do it, everyone can. { "name": "Generate Free WordPress Post with Form and OpenRouter", "nodes": [ { "parameters": { "path": "create-post", "formTitle": "Create WordPress Post", "formDescription": "Enter the data to generate or rewrite a WordPress post", "formFields": { "values": [ {"fieldLabel": "Keywords (comma-separated)", "requiredField": true}, {"fieldLabel": "Number of Chapters", "fieldType": "dropdown", "fieldOptions": {"values": [{"option": "1"}, {"option": "2"}, {"option": "3"}, {"option": "4"}, {"option": "5"}]}, "requiredField": true}, {"fieldLabel": "Maximum Word Count", "fieldType": "number", "requiredField": true}, {"fieldLabel": "Original Text", "fieldType": "textArea", "requiredField": false, "description": "Enter the text you want the AI to rewrite into a blog post.
